Despite research into the development of digital cognitive behavioral therapy for insomnia (dCBT-I), research into the outcomes of dCBT-I on insomnia and the associated clinical conditions of depression and anxiety have been limited. The PubMed, PsycINFO (Ovid), Embase, and Cochrane databases were searched for randomized controlled trials (RCTs) on adult patients with insomnia also having reported measures of depressive or anxiety symptoms. In total, 2504 articles were identified after duplicate removal, and 22 RCTs were included in the final meta-analysis. At the post-treatment assessment, the dCBT-I group had a small to moderate effect in alleviating depressive (standardized mean difference (SMD) = −0.42; 95% CI: −0.56, −0.28; p < 0.001; k = 21) and anxiety symptoms (SMD = −0.29; 95% CI: −0.40, −0.19; p < 0.001; k = 18), but had a large effect on sleep outcome measures (SMD = −0.76; 95% CI: −0.95, −0.57; p < 0.001; k = 22). When considering treatment adherence, the treatment effects of those in the high adherent groups identified a more robust outcome, showing greater effect sizes than those in the low adherent groups for depression, anxiety, and sleep outcomes. Furthermore, additional subgroup analysis on studies that have used the fully automated dCBT-I treatment without the support of human therapists reported significant treatment effects for depression, anxiety, and sleep outcomes. The results demonstrated that digital intervention for insomnia yielded significant effects on alleviating depressive and anxiety symptoms as well as insomnia symptoms. Specifically, the study demonstrated significant effects on the above symptoms when considering treatment adherence and implementing fully automated dCBT-I.
Digital therapeutics (DTx) are products that provide evidence-based interventions driven by high-quality software programs to prevent, manage, or treat a medical disease. DTx are receiving increasing attention as a new therapeutic approach. Several DTx for insomnia are on the market, some of which have received approval by national regulatory agencies. DTx for insomnia are usually based on cognitive behavioral therapy for insomnia. No DTx for other sleep disorders, such as narcolepsy or sleep-related breathing disorders, have received regulatory authority approval as a medical device. DTx have the substantial benefits of being accessible and relatively low-cost. However, several issues related to DTx have not yet been fully resolved, and discussions regarding DTx are still in the early stages. To use DTx for sleep disorders as an effective treatment option in the future, considering the current status of DTx is necessary. This review discusses definitions and background of DTx; specific DTx for insomnia that have been developed; use of DTx for sleep and related psychiatric comorbid symptoms; global regulatory processes for DTx, including prescribing and medical billing issues; and remaining challenges regarding the use of DTx.
Background: Experiences of negative social interactions and childhood trauma (CT) can lead to aberrant hypothalamic–pituitary–adrenal functions. Poor theory of mind (ToM) ability is related to increased social stress levels; however, studies on the relationship between ToM and cortisol remain scarce. Objective: This study aimed to evaluate the relationship between ToM and the hair cortisol concentration (HCC) in healthy young adults considering the moderating role of CT. Method: A total of 206 healthy young adults were divided into two groups based on an experience of moderate-to-severe childhood trauma (CT+ and CT–). To determine whether CT moderated the relationship between ToM and HCC, moderation analysis was conducted controlling for age, sex, years of education, and scores of perceived stress, depression, and anxiety. Results: CT+ individuals reported higher subjective stress perception and depressive symptoms than CT– individuals, whereas anxiety-related symptoms, ToM, and HCC were not different between the groups. The experience of CT significantly moderated the relationship between ToM and HCC. The association between poorer ToM ability and higher HCC was significant only in CT+ group. Conclusion: CT is a moderator of the association between ToM and HCC, indicating the importance of CT in social cognition and the stress response.
Objective: This study aims to examine clinical characteristics and to identify possible risk factors of sleep disturbances in people living with HIV (PLWH).Methods: All research data of patients who were first diagnosed with HIV/AIDS from January 1, 2012 to December 31, 2021 and complained of sleep disturbance at least once were retrospectively reviewed by the Severance Clinical Research Analysis Portal (SCRAP) service of Severance hospital. The presence of sleep disturbance was evaluated based on whether insomnia disorder diagnosis code was included or whether insomnia medication was prescribed. The patients were divided into either the group with sleep disturbance within 3 months (SDW3) and the group with after 3 months (SDA3). All data were reported using descriptive statistics.Results: Of the 674 patients diagnosed with HIV during the period, 56 patients experienced sleep disturbances at least once and approximately 50% of patients have experienced sleep disturbance in the first 3 months after HIV diagnosis. CD4+ cell count at the time of first onset of sleep disturbance was significantly lower (p=0.03) and HIV viral load at the time of first onset of sleep disturbance was significantly higher (p<0.001) in SDW3 group. SDW3 patients showed higher rates of opportunistic infections compared to SDA3 patients.Conclusion: The current study suggests that further investigation of the underlying pathophysiology of sleep disturbance and association with immunological changes for early diagnosis and treatment of sleep disturbance in PLWH.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
